PROBLEM TO BE SOLVED: To provide a battery system in which dust (dust containing fine grains having a diameter of 5 μm or less) discharged from the interior of a lithium ion secondary battery can be captured in a cooling gas passage.SOLUTION: A battery system 80 includes abnormality detection means (resistance measuring device 71) for detecting abnormality of one or a plurality of lithium ion secondary batteries 100, a liquid spray 10 for spraying liquid into a cooling gas passage F (cooling medium passage), and control means (controller 50) for controlling the liquid spray 10. When abnormality is detected in one or a plurality of lithium ion secondary batteries 100 by the abnormality detection means, the controller 50 controls the liquid spray 10 to spray liquid into the cooling gas passage F. |
